DETAILED DESCRIPTION

Embodiments of the present invention address technical challenges with security systems. Typically, a security system is static in nature. Security systems provide protection from threats to security such as burglary, vandalism arson, etc. The security system is used for the safety and protection of personnel, property and surroundings. The security system operates by monitoring one or more sensors that are placed at predetermined locations around a building that is being protected by the security system. The sensors can include, but not limited to, motion detectors, light sensors, door sensors, noise sensors, humidity sensors, heat sensors, cameras, window sensors, glass-breakage sensors, infrared sensors, etc. A base station of the security system monitors a security-breach indicated by any of the sensors. The base station and the sensors communicate with each other using wired and/or wireless communication protocols.

A technical challenge with the existing security systems is that they are static. That is, a security system can only offer protection to the building based on the existing sensors of the security system, which are placed in the one or more predetermined locations around the building. For example, the sensors can be placed at doors, windows, high-traffic areas, or other such locations based on human judgment. While such placement of the sensors may suffice for a residence, an office, a small business, a restaurant, or other such buildings that have designated or limited entry and/or exit points, the security system cannot be used in buildings such as parking garages, parks, driveways, yards, etc. where entry and exits are not limited. In such spaces, where a culprit, for example, a burglar, arsonist, etc. can access the space from any direction, and without designated doors and/or windows, placing the sensors can be a challenge. Accordingly, such spaces go unmonitored. Alternatively, in some examples, cameras are relied upon to monitor such spaces. However, such monitoring only facilitates analyzing a security-breach that has occurred in the past, and after the culprit has long fled. Prompt action for a possible intervention during or immediately after the security-breach in such spaces is a technical challenge with existing security systems. Here, “immediately” after the security-breach can include within a predetermined duration since the start of the security-breach, for example, 20 minutes, 40 minutes, or any other such predetermined duration in which first responders, such as police, firefighters, paramedics, can arrive at the scene of the security-breach.

Embodiments of the technical solutions described herein address such technical challenges. Further, embodiments described herein address problems such as an increase in break-ins or theft of property, such as vehicles, boats, shipment packages, and other such items that may typically be parked or placed outside the premises, where the premises are typically secured using a security system. For example, vehicles, boats, recreational vehicles, and other such items may be placed on a driveway. Further, shipment packages are placed in the yard for pickup, or upon receipt. While some of these items, such as vehicles, have their own security systems, these security systems are localized, and typically are limited to blaring of an alarm, flashing of lights, and other such localized signals.

Embodiments of the technical solutions described herein facilitate the security systems for such items to be dynamically connected to a security system of a building, where the item is in the vicinity of that building. The security system of the building is actively monitored, and facilitates to generate local as well as remote alarms in response to a breach of the security of the item.

Embodiments of the technical solutions described herein facilitate a security system to be expanded to monitor such spaces, where designated entry/exits are not available. Embodiments of the technical solution facilitate a first security system to be expanded by adding another security system as one of the sensors that are monitored by a base station of the first security system.

FIG. 1 depicts a block diagram of an expandable security system according to one or more embodiments. The system 100 includes a security system 101, referred herein as a “central security system.” The central security system 101 includes a base station 102 that monitors one or more sensors 104. The sensors 104 are placed at predetermined locations in an area 106. The area 106 can be part of a building 108 such as a residence, an office, a shop, a restaurant, a school, or any other building. The area 106 is protected by the security system 101. The sensors 104 can be placed at doors 120, windows 122, or other such locations, such as a hallway, stairs, etc. The base station 102 monitors the sensors 104 for a security-breach, in response to which the base station 102 generates an alarm event.

The alarm event can include a predetermined audible sound, for example, higher than a predetermined decibel value using audio speaker(s) 114. The alarm event can also include a visual notification, such as switching a light ON, flashing lights, strobing lights, or any other such visual indications using light emitting device(s) 118. The alarm event can further include sending wired or wireless communications to one or more devices to notify of the security breach. In response, recipients of the notification can try intervening the security breach, such as, by apprehending a culprit that causes the security breach, attending to a medical emergency, preventing fire from spreading, etc. For example, the recipients can include police, firefighters, paramedics, neighbors, relatives, friends, of a user of the security system 101, or the user him/herself. For such notifications, the base station 102 sends notification communications to be received by communication devices associated with such personnel. FIG. 1 depicts a control device 105 that can be such a communication device associated with a user of the security system 101.

The control device 105 can be a control panel associated with the security system 101.

Alternatively the control device 105 can be a communication device such as, a phone, a tablet computer, a laptop computer, a server computer, a desktop computer, or any other such communication device that can receive the notification communicated by the base station 102.

The building 108 can further include an area 110 that is not monitored by the security system 101. The area 110 is not covered by the security system 101 because of a lack of sensors 104 in the area 110. The area 110 can be a yard, a driveway, parking areas or a parking garage, a porch, boat moorage, bicycle stand, a shed, a gazebo, a sunroom, or any other such structure that is not part of the area 106 that is covered by the security system 101. It is understood that the depiction of the area 110, the building 108, and the area 106 in FIG. 1 is exemplary, and that in other embodiments, the orientation of the building 108, and the areas 106, 110 can vary from the depiction. In an example, the area 110 can be another structure that is attached to/with the building 108. Embodiments described herein facilitate expanding the perimeter of the security system 101 dynamically.

Accordingly, as described earlier, an item 130 that is in the area 110 is typically not protected by the security system 101. The item 130 can be a shipment package, a furniture item, a bike, a toy, a vehicle or any other such item. It should be understood that although only a single item 130 is shown, in one or more embodiments the area 110 can include multiple items 130. For example, the area 110 can encompass one or more vehicles, bikes, furniture items, etc.

In an example, the building 108 can be a parking garage, with the security system 101 being a central security system that secures the area 106, such as where an office of the parking garage exists in the building 108, or any other such area. The sensors 104 can include cameras, radio frequency identification (RFID) scanners, garage-entry ticket machines, or any other garage entry device that provides access to a parking garage. The vast portion of the parking garage, where one or more patrons park their vehicles may not be protected by the security system 101. Hence, typically, patrons are warned that their vehicles and belonging in such vehicles are not being secured.

In an example, the item 130 has a security system 101B of its own. The security system 101B includes a base station 102B, a control device 105B, and a set of sensors 104B of its own. For example, in the above example with the item 130 being a vehicle, the security system 101B can be a security system of the vehicle. The security system 101B can include its own audio devices 114 and light emitting devices 118 in one or more embodiments. The operation of the security system 101B is similar to that of the security system 101, and hence, not repeated herein.

The security system 101 and the security system 101B can operate in several modes. The modes can include a protect-mode, a sleep-mode, among other modes. By default, in one or more embodiments of the present invention, the security system 101/101B is in the sleep-mode. The security system 101/101B can be put in one of the modes by sending a signal to the base station 102/102B to change the operational mode. Alternatively, or in addition, such a signal can be input via the control device 105/105B.

In the protect-mode the security system 101/101B provides anti-theft protection to the area 106 and/or the item 130 that is assigned to the security system 101/101B. In the protect-mode, the security system 101/101B, using the sensors 104/104B, detects a movement, break-in, or any other unauthorized action with the area/item assigned to the security system 101/101B. In response, the security system 101/101B causes an alarm to sound. For example, the audio speaker 114 can be used to generate an audible alarm. In addition, or alternatively, the base station 102/102B can send a notification to a server, such as a notification center (not shown), as part of the alarm. In addition, or alternatively, the base station 102/102B can send a notification to a user associated with the security system 101/101B. The base station 102/102B can be programmed where to send the message notification.

The security system 101/101B can further provide an audio/visual notification that can deter a theft of the item 130 and any other property in the protected area 106. For example, the audio speaker 114 and/or the light emitting device 118 can provide the audiovisual notification. The audiovisual notification can include an alarm sound, a flashing light pattern, or any other combination.

In the sleep-mode the security system 101/101B does not monitor a security-breach using the sensors 104/104B. In one or more embodiments, the sensors 104/104B are put in a power saving mode. Accordingly, in sleep-mode, an alarm event cannot be raised by the security system 101/101B.

FIG. 2 depicts a flowchart of a method for expanding the security system according to one or more embodiments. The method 200 that is depicted is described in context of FIG. 1, with reference to the security system 101 as a central security system, and the security system 101B as a portable security system. As described herein, the central security system can be a security system of a building (e.g., public garage, home, private garage, etc.), and the portable security system can be a security system of a vehicle that is being parked in the building. It is understood that other example scenarios can also exist, such as, the central security system being that of a building (e.g., home, office, etc.), and the portable security system being that of a vehicle, shipment package, furniture, or any other item 130 that is in the vicinity of the building. The method 200 facilitates expanding the central security system using the portable security system.

The method 200 includes, at block 202, receiving, by the base station 102 of the central security system 101, identification of the portable security system 101B. It is understood that the method 200 is described with respect to only one portable security system 101B, however, the method is applicable to multiple portable security systems 101B to be configured to be added to the security system 101. In other words, the security system 101 can be expanded using one or more portable security systems 101B simultaneously. Further, the any one or more of the portable security systems 101B that have been added to the security system 101 can be dynamically added and/or removed, making the coverage of the security system 101 dynamic, i.e., vary at runtime.

The identification of the portable security system 101B is received by scanning an identifier associated with the portable security system 101B via a sensor 104 of the central security system 101. For example, the portable security system 101B can be associated with an identification device, which is scanned by the sensor 104 of the central security system 101. The identification device can be a radio frequency identification (RFID) device, a mobile, or any other such device that is associated with the portable security system 101B. The identification device can also be a card with a barcode, a QR-code, an image, or any other such machine-readable identification code. Alternatively, the identification of the portable security system 101B can be received via a near-field communication, such as using BLUETOOTH®, ZIGBEE®, or any other such communication protocols. The machine-readable code is a unique code associated with the portable security system 101B. The sensor 104 of the central security system 101 can be an RFID scanner, a camera, a code reader, a near-field communicator, or any other such device. In one or more embodiments, the sensor 104 can facilitate a manual entry of the identification of the portable security system 101B. For example, the device can include a keypad (not shown) that facilitates manual entry of the identification information. Alternatively, or in addition, the identification of the portable security system 101B can be received by the base station 102 via internet-of-things (IoT), or any other communication technique that uses the Internet.

At block 204, the base station 102 of the central security system 101 adds the portable security system 101B as a sensor 104. The portable security system 101B can be added to the set of sensors 104 that is monitored by the base station 102. The base station 102 includes a list 250 (FIG. 3) of sensors 104 that it monitors. The list 250 can be maintained as a data structure, such as an array, a database table, or any other electronic data structure. The list 250 can be stored in a memory and/or storage disk of the base station 102. The portable security system 101B is added to the list 250. In an example, each entry of the list 250 of sensors in the base station 102 includes at least an identifier and type of the sensor 104 that is being monitored by the base station 102. The list 250 can include additional information, such as location, time at which the sensor was added to the list 250, etc., in some embodiments. In an embodiment, the base station 102 sends a confirmation to the portable security system 101B that it has been added as one of the sensors 104. The confirmation can include a code that the base station 102 assigns the portable security system in one or more embodiments.

In one or more embodiments, at block 206, the base station 102, upon receiving the identification, verifies that the identification is associated with an account associated with an authorized user. An “authorized user” here is an entity that has authorized any payment that may be required by the base station 102 to monitor the portable security system 101B. The authorized user can maintain an account for such payments. The account and/or the authorized user are associated with the identifier of the portable security system 101B. In an example, the base station 102 verifies that the portable security system 101B is associated with the authorized user (or account) by cross-referencing with another database table, or any other data structure. If the identifier does not refer to an authorized user/account, the base station 102 can decline adding the portable security system 101B to the list 250. In one or more embodiments, a user of the portable security system 101B can receive a notification, for example via the sensor being used to scan the identification information, that the addition was declined. The user of the portable security system 101B can add the authorized user/account information via a separate interface (not shown) and subsequently scan the identification information again.

In an example, adding the portable security system 101B to the list 250 of the base station 102 includes initiating a communication link with the portable security system 101B. The communication can occur via one of the communication protocols such as BLUETOOTH®, ZIGBEE®, or using known techniques for internet-of-things (IoT) etc. In one or more embodiments, the entry in the list 250 corresponding to the portable security system 101B includes a communication address associated with the portable security system 101B. For example, the communication address can include an internet protocol (IP) address, a port number, or any other type of communication address for the base station 102 to communicate with the portable security system 101B. In one or more examples, the communication address of the portable security system 101B is associated with the base station 102B of the portable security system 101B. The type of communication address depends on the communication protocol that is used to communicate with the portable security system 101B. In one or more embodiments, the base station 102 communicates with a first portable security system 101B via a first communication protocol, such as ZIGBEE®, and with a second portable security system 101B via a second communication protocol, such as ZWAVE®. The communications between the base stations 102 and 102B can be encrypted or secured in any other manner.

At block 208, the base station 102 configures the portable security system 101B in protect-mode. The base station 102 can send a signal to the portable security system 101B to make this transition. In one or more embodiments, the transition to the protect-mode occurs after a predetermined duration since the scanning of the identification of the portable security system 101B. In yet other embodiments, the base station 102 sends the signal to transition the portable security system 101B to protect-mode in response to receiving a notification from the user of the portable security system 101B.

For example, consider the case where the portable security system 101B is associated with a vehicle and the central security system 101 is a security system for the entire garage in which the vehicle is going to be parked. The user (e.g., driver of the vehicle) scans an identification of the portable security system 101B, for example, by scanning a parking pass, a parking entry card, a license tag of the vehicle, an RFID chip, a mobile phone, or any other form of identification that is associated with the vehicle, which in turn is associated with the portable security system 101B. In an example, the user enters the identification manually. The central security system 101 registers the portable security system 101B as a sensor 104. Further, after the user parks the vehicle, s/he can notify the central security system 101 to switch the vehicle into the protect-mode. For example, the user can send the notification using a mobile phone, a device placed in the parking spot, the portable security system 101B, or using other such technique. Alternatively, or in addition, the central security system 101 transitions the portable security system 101B to the protect-mode after a predetermined duration after the scanning of the identification by the user.

During the configuring of the portable security system 101B into protect-mode, the portable security system 101B provides a predetermined wait-period to complete the transition. For example, upon receiving an instruction from the central security system 101 to transition into the protect-mode, the portable security system 101B initiates a timer of a predetermined wait-period, for example, 30 seconds, 1 minute, etc., or any other configurable duration. In one or more embodiments, the portable security system 101B provides an audio/visual indication, for example, an audible beep, a flashing light, etc., that the protect-mode is being initiated. During this wait-period, the user can cancel the transition. For example, the user can send a cancellation to the central security system 101 via a mobile device, a device in the parking garage, the portable security system 101B, or any other techniques. The user can instruct the central security system 101 to transition into the protect-mode when s/he is ready. Such an instruction can be sent a mobile device, a device in the parking garage, the portable security system 101B, or any other techniques.

Alternatively, consider the case where the portable security system 101B is associated with a shipment package and the central security system 101 is a security system for a house, an office, a building, etc., where the shipment package is to be delivered and/or stored. The user (e.g., shipment delivery person) scans an identification of the portable security system 101B, for example, by scanning his/her identification, shipment package identification, an RFID tag/chip, a mobile phone, or any other form of identification(s) associated with the shipment package, which is associated with the portable security system 101B. Several other such examples where the embodiments herein can be used can be realized by a person skilled in the art, and each and every such example is not listed herein.

It should be noted that only the portable security system 101B that is identified and/or requested is transitioned to protect-mode, and the operational mode of other sensors 104 of the security system 101 is not changed. Consider the case that the security system 101 is monitoring multiple portable security systems 101B, for example, a first portable security system of a first vehicle, and a second portable security system of a second vehicle. A first authorized user associated with the first vehicle can transition the operational mode of the first security system from protect-mode to sleep-mode, and vice versa, and such transition does not affect the operational mode of the second security system. For example, the second security system can be in sleep-mode (or protect-mode) during such transitions with the first security system. Accordingly, the security system 101 can be dynamically expanded.

Further, the transition of the operational mode of the first security system does not affect the operational mode of other sensors 104 of the security system 101. For example, if the security system 101 includes a door sensor, a window sensor, a motion sensor, etc., the operational mode of these sensors are not affected by the transition of the operational mode of the portable security system 101B.

Once the portable security system 101B is transitioned into the protect-mode, the central security system 101 monitors the portable security system 101B for any security breach, at block 210. The security breach can include the portable security system 101B being displaced by more than a predetermined threshold, for example, over 5 meters, 10 meters, or any other such configurable threshold. The security breach can further include a break-in, glass-break, water-leak, an impact, or any other such events that are detected using one or more sensors 104B of the portable security system 101B. The base station 102 of the central security system 101 monitors the portable security system 101B by monitoring if any of the sensors 104B has detected any such security breach. In one or more embodiments, the sensors 104B send an indication of the security breach to the base station 102B of the portable security system 101B, which in turn sends the notification of the security breach to the base station 102 of the central security system 101. The monitoring is performed continuously.

At block 212, if a security breach is not detected, the monitoring (210) continues as described herein, at least until a breach is detected or until the operating mode of the portable security system 101B is changed. Alternatively, if a security breach is detected (212), the base station 102 sounds an alarm, at block 214. The alarm can include generating an alarm event as described herein.

Accordingly, the central security system 101 can be expanded to monitor the security of the item 130, for example, the vehicle, using the portable security system 101B that is associated with the item 130. The alarm event that the central security system 101 generates is an improvement over the alarm event that the portable security system 101B typically generates. For example, the alarm event that the portable security system 101B generates is local, such as, an audible alarm, whereas the central security system 101 can generate a multifaceted alarm event as described herein, that can even result in security personnel intervening the security breach.

Further, at block 216, the central security system 101 changes the portable security system 101B into the sleep-mode upon receiving an instruction to do so. The instruction can be received via the control device 105 or the sensors 104 of the central security system 101. Alternatively, the instruction can be received via a device in the parking garage (e.g., a parking meter), or any other such device. Alternatively, the instruction can be provided via the base station 102B, the sensors 104B, or any other device of the portable security system 101B. In one or more embodiments, the central security system 101 validates that the instruction is received from an authorized user/device associated with the portable security system 101B. Accordingly, the central security system 101 ensures that only an authorized user is able to change the operational mode of the item 130.

Further, at block 220, the base station 102 removes the portable security system 101B from the list 250 of sensors 104 of the central security system 101. In an embodiment, the base station 102 removes the portable security system 101B from the list 250 in response to an instruction to remove the portable security system 101B, which is separate from the instruction to transition the portable security system 101B into the sleep-mode. In another embodiment, the instruction to remove the portable security system 101B can be combined with the instruction to transition the portable security system 101B into the sleep-mode. Once, the portable security system 101B is removed from the list 250, the base station 102 of the central security system 101 does not monitor the portable security system 101B for security breaches. The base station 102 does not monitor the portable security system 101B also in the sleep-mode; however, in the portable security system 101B can be transitioned back to the protect-mode from the sleep-mode causing the base station 102 to restart the monitoring. In an embodiment, the base station 102 sends a confirmation to the portable security system 101B that it has been removed as one of the sensors 104.

FIG. 4 depicts a state transition diagram for the various states in which the portable security system 101B can be programmed according to one or more embodiments. The portable security system 101B can be placed in the protect-mode (1004) at the initial identification and addition of the portable security system 101B to the central security system 101. The authorized user can transition the portable security system 101B, from the protect-mode, into the sleep-mode (1010) once monitoring is to be stopped. Alternatively, if the item 130 is accessed in an unauthorized manner, i.e., displaced beyond a threshold, without providing authorization, the portable security system 101B, and in turn, the central security system 101, enters into the alarm-mode (1002). The alarm is sounded in the alarm-mode (1002), including a local audiovisual notification, remote audiovisual notification, requesting security personnel (e.g., police) to intervene, etc. The shipment device 130 can be transitioned from the alarm-mode (1002) to the sleep-mode (1010) by providing authorization, for example, security code, scanning identification, or in any other manner.

Turning now to FIG. 5, a computer system 300 is generally shown in accordance with an embodiment. The computer system 300 can be used as a base station, sensor, or the security system(s) as described herein. The computer system 300 can be an electronic, computer framework comprising and/or employing any number and combination of computing devices and networks utilizing various communication technologies, as described herein. The computer system 300 can be easily scalable, extensible, and modular, with the ability to change to different services or reconfigure some features independently of others. The computer system 300 may be, for example, a server, desktop computer, laptop computer, tablet computer, or smartphone. In some examples, computer system 300 may be a cloud computing node.

FIG. 6 depicts a block diagram of a portable security device 600 according to one or more embodiments. The portable security device 600 can be used as the portable security system 101B. For example, the portable security device 600 can be placed inside, on, or in any other association with a vehicle, a boat, a shipment package, or any other item 130 that is to be protected. The portable security device 600 can communicate with the base station 102 of the central security system 101 to provide security protection to the item 130, and further to expand the coverage of the central security system 101.

The portable security device 600 includes a memory device 602, and a processor 604.

The portable security device 600 also includes a power source 620 that provides electric power to the processor 604, the memory device 602, and other components of the portable security device 600. The power source 620 can be charged using an electric connection (not shown), solar power, or any other source of power. The processor 604 can include several processing units, such as one or more processing cores, a graphics processing unit, a digital signal processing unit, an arithmetic logic unit, and other such types of processing units. The processor 604 is coupled with the memory device 602 to facilitate execution of one or more computer executable instructions. In one or more embodiments, the memory device 602 includes computer executable instructions.

The memory device 602 can include volatile memory and non-volatile memory. In one or more embodiments of the invention, data stored on the non-volatile memory may be encrypted.

In addition, the portable security device 600 includes a set of sensors 640. The set of sensors can include a location sensor 606, a gyroscope 608, an accelerometer 610, an image sensor 612 (camera) and other sensors. The portable security device 600 also includes an audio emitting device 614, such as an audio speaker. The portable security device 600 further includes a light emitting device 618, such as a light emitting diode (LED) lamp, or any other type of visual indicator. The light emitting device 618 can be caused to light up, start flashing, or perform any other pattern to indicate a visual warning. In an embodiment, the visual warning may be for a camera or another sensor of the central security system 101. In one or more embodiments, the light emitting device 618 emits light using a frequency that is not visible to human eye, for example, using an infrared frequency. Alternatively, or in addition, the light emitting device 618 emits a notification that can be seen by human eye. The portable security device 600 also includes a keypad 650. The keypad 650 can include one or more buttons or other user interface elements.

The portable security device 600 includes a communication module 616 that facilitates one or more modes of communication to/from the processor 604 with one or more external devices. For example, the communication module 616 can facilitate a wired communication. In addition, the communication module 616 can facilitate wireless communication. For example, the communication module 616 can communicate signals for reception by the base station 102 of the central security system 101 using the Internet using Wi-Fi, LTE, 3G, or any other type of communication networks. The communication module 616 can also include hardware and corresponding software that facilitate near field communication, using communication protocols such as BLUETOOTH, Z-WAVE, or any other such communication protocols. The communication module 616 facilitates communication to/from the portable security device 600.

The communication module 616 facilitates external devices, such as the base station 102 to send signals and data to the portable security device 600. For example, the base station 102 can configure the portable security device 600. Such configuring can include changing an operational mode of the portable security device 600. Configuring the portable security device 600 includes transferring data that can include one or more computer executable instructions to the portable security device 600. In addition, the data can include images, codes, parameter values (text, numbers, or other characters), and other such data that is used during execution of one or more computer executable instructions by the processor 604.

The portable security device 600 can operate in the protect-mode and the sleep-mode among other modes. The portable security device 600 can be put in one of the modes by sending a signal to change the operational mode. Such a signal can be sent via the communication module 616. Alternatively, or in addition, such a signal can be input via the keypad 650.

In the protect-mode the portable security device 600 secures the item 130 that is assigned to the portable security device 600 by monitoring the sensors 640. In the sleep-mode the sensors 640 are not monitored.

In the protect-mode, the processor 604, using the sensors 640, detects a security breach of the item 130. For example, if the movement of the item 130 is beyond a predetermined threshold, the processor 604 raises an alarm. For example, the audio speaker 614 can be used to generate an audible alarm. In addition, or alternatively, the processor 604 can send a notification to the base station 102 as part of the alarm. In addition, or alternatively, the processor 604 can send a notification to the authorized user. The security breach that is detected can be different from the movement beyond a threshold. For example, the security breach can include an event such as glass breakage, door opening, window opening, hit-and-run, or any other event detected by the sensors of the portable security device 600.

The portable security device 600 can further provide an audio/visual notification that can deter a theft of the item 130. For example, the audio speaker 614 and/or the light emitting device 618 can provide the audiovisual notification. The audiovisual notification can include an alarm sound, a flashing light pattern, or any other combination.

In addition, the portable security device 600 can be monitored using a base station 102 of the central security system 101. In such cases, the portable security device 600 can send a notification to the base station 102 that causes the base station 102 to sound an alarm as per one or more settings of the security system 101. In an embodiment, the notification to the base station 102 can be sent via a communication protocol such as BLUETOOTH, Z-WAVE, ZIGBEE, or any other such communication protocols that can be used for secure communication between security devices. Alternatively or in addition, the portable security device 600 can provide the notification to the base station 102 using the audio speakers 614 and/or the light emitting device 618. For example, the portable security device 600 can emit an audio or visual signal that is recognized by one or more sensors 104 of the central security system 101, that in turn, cause the base station 102 to sound the alarm. In an example, the audio/light signal(s) emitted by the portable security device 600 cannot be heard or seen by human eye.

Further, the communication can also be delivered to the authorized user listed in the database 250. The communication can be sent as a notification to a communication device, such as a phone, wearable, etc., using one or more communication protocols/techniques. For example, the communication can be sent using short messaging service (SMS), instant message, email, phone call, application-notification, or using any other communication technique.

The portable security device 600 facilitates ensuring that the item 139 is secured by the central security system 101 of a premise, such as a building where the item 130 is in the vicinity of the premise, as described herein.

For example, consider an example scenario where a user drives a vehicle to a restaurant. The user adds a portable security system associated with the vehicle to a central security system provided by the restaurant, parking garage, government, or any other parking facility provider. In one embodiment, the portable security system can be a security system that is inbuilt in the vehicle. Alternatively, the portable security system is a portable security device that is placed in the vehicle. The portable security device can belong to the user, the parking facility provider, or any other entity. The user can have the portable security device to transition into protect-mode until the user is at the restaurant (or any other store, office, etc.). Once the user has completed his/her visit, the user can have the portable security device transition back to sleep-mode, and use his/her vehicle. It should be noted that although a particular example scenario is described, other such application scenarios where one or more embodiments described herein are used to protect an item by dynamically expanding a central security system would be obvious to a person skilled in the art.

Embodiments of the technical solutions described herein provide a practical application to prevent a security-breach in areas that are typically left unattended by existing security systems by facilitating an expandable security system that can cascade multiple security systems together. Embodiments described herein facilitate a security system to be expanded so that the premises that are protected by the security system can be dynamically adjusted. For example, additional security systems can be added to a base station of security system that is assigned to protect a building. The additional security systems can be associated with one or more items/entities that are in the areas such as driveway, parking garage, yard, or other such typically unattended areas. The base station adds the security systems as sensors. A security-breach associated with the additional security systems is handled by the base station as a trigger to raise an alarm of its own. Accordingly, embodiments described herein provide a dynamic extension/expansion of security of a movable object, such as a vehicle, boat, package, etc.

Further, embodiments described herein facilitate a security system to monitor only a subset of the sensors that are dynamically added and/or removed from the security system. In comparison, in existing security systems, either all sensors of a security system are monitored or none.

It should be noted that during all of the operations described herein, the base station can facilitate a predetermined duration to pass before a transitioning an additional security system from one state to another. For example, when transitioning the additional security system from one mode (e.g., sleep-mode) to another (e.g., protect-mode), sounding an alarm, or any other such state transition, the base station waits for at least the predetermined duration before the state is updated. The base station may provide an indication of the transition, for example, via an audible or visual notification. The notification can be provided via the speakers 114, the lights 116, and/or the second security system 101B.
